A Bleed From the Distal Anastomosis Site of a Bypass Graft From the Left Common Iliac Artery to the Celiac Trunk Treated With a Surgeon-Modified Fenestrated Endograft

Abstract

Purpose:

The use of surgeon-modified fenestrated endograft to treat a bleeding complication in the common iliac artery.

Technique:

An Endurant limb graft was modified on back table in theater after planning the fenestration using a semi-automated centerline. The Endurant stent was planned to land flush at the aortic bifurcation. The Endurant limb was partially deployed until the fenestration opened facing the anastomosis to enable rotation and axial movement of the stent graft, if needed. By obtaining access from the contralateral common femoral artery, the fenestration was cannulated using up-and-over technique and bypass graft cannulated. The Endurant stent graft was then fully deployed. Through a separate puncture in the ipsilateral sheath, the fenestration was re-cannulated using a hydrophilic wire, and a balloon-expandable covered stent was introduced through a 7F sheath and then flared in a kissing fashion along with the Endurant stent. The distal part of the Endurant limb was extended with a bare metal stent into the external iliac artery. Control angiography was satisfactory, and bleeding was controlled.

Conclusion:

Surgeon-modified stent graft in the iliac arteries can be used even in the context of non-aneurysmal disease to treat patients in high-risk emergency situations and could be part of the armamentarium of the vascular surgeon.

Clinical Impact

Physician-modified endografts are increasingly being used by vascular surgeons and interventional radiologists to treat patients with complex aorto-iliac aneurysms in whom custom-made endograft provided by the manufacturer is too expensive to produce and/or patient requires urgent surgery. Data on the use of physician-modified endografts to treat non-aneurysmal disease is lacking. This technical note highlights the use of physician-modified endograft to treat a patient with bleeding complication from the distal anastomosis of an iliac artery to coeliac trunk bypass graft in whom open surgery posed unacceptable high morbidity and mortality risks. This technical note continues to add more information and knowledge to the vascular surgery / interventional radiology communities on the use of physician-modified endografts and also adds another tool in the armamentarium of teams involved.
